The question that is not being asked is, who will the DNC launch in 2016?

Biden? I don't think so.

Hillary? She'll 69 on Election Day in 2016. she has developed much goodwill as SoS, and is building plenty of political capital among rank-and-file Democrats and Moderates. There is no reason why she could not be the DNC candidate in 2016; at a minimum, she would be every bit as viable as she was in 2008, and she would quite likely be the odds-on favorite for the nomination in 2016.

If Hillary decides to retire, (she's earned it) there are a few other woman potentials in the wings;

Kirsten Gillibrand - Senator from New York State is a rising star in the Democratic Party. She could be ready by '016 (she will only be 49 on election day)

New York City Mayor Michael Bloomberg, has lots of money and has served longer consecutive terms as mayor of NYC than anyone. He has thrown his hat into the race as an Independent, and has garnered support early from Wall Street and business tycoons as well as moderate Republicans. but because of his deep pockets, would likely get support from the DNC

and would you believe;

Rahm Emanuel, he is a former Illinois congressman and White House Chief-of-Staff for President Obama, he has an impeccable record of "getting things done." If he wins his race for mayor of Chicago, and he probably will, he could use that high profile job to make a run for Pres. (2016 is a long way off on the political time clock) He could be the first viable Jewish candidate for the presidency and could well have the credentials by then.
